[0002] On the side of an urban bridge deck is often a sidewalk. In order to prevent pedestrians from falling into the river below, guardrails need to be installed on the side of the sidewalk.
[0003] Currently, a Chinese patent with the publication number CN218373544U and the publication date of January 24, 2023 discloses an isolation device for a green belt on an urban road, including an upper crossbar, a lower crossbar, railing bars and columns. An upper crossbar and a lower crossbar are respectively arranged between the upper and lower sides of two columns. The railing bars and the columns are both bent structures with the upper ends inclined towards the sidewalk. The area between the vertical projections of the two columns on the sidewalk is an inclined downward slope curb, and there is a gap between the railing bars and the slope curb.
[0004] In this kind of isolation device for a green belt on an urban road, the railing bars are usually welded to the upper crossbar. Therefore, when one of the railing bars is damaged and needs to be replaced, the damaged railing bar needs to be cut off from the crossbar before a new railing bar can be welded. Eventually, the replacement of the railing bars will be very time-consuming and laborious. Content of the Utility Model
[0005] The purpose of the utility model is to provide a sidewalk guardrail structure for a municipal bridge deck, which is beneficial to the replacement of the crossbar.
[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A sidewalk guardrail structure for a municipal bridge deck includes multiple arc-shaped columns evenly spaced along the extending direction of the sidewalk, and multiple crossbars arranged between adjacent arc-shaped columns. The crossbar includes a central rod, a first adjusting rod arranged at one end of the central rod, and a second adjusting rod arranged at the other end of the central rod. First internal thread grooves are opened in both ends of the central rod. Threaded ends that are threadedly connected in the first internal thread grooves are arranged at one ends of the first adjusting rod and the second adjusting rod. Card slots for embedding the ends of the first adjusting rod and the second adjusting rod far from the central rod are opened on both sides of the arc-shaped column. A second internal thread groove is opened on the end surface of the end of the first adjusting rod far from the central rod. A splicing threaded column for being threadedly connected in the second internal thread groove is arranged on the end surface of the end of the second adjusting rod far from the central rod.
